Frame Rails



One of the best performance upgrades for the Miata! Frame rails aid in additional rigidity to the MX5 Miata uni-body. Our rails are made from 14 gauge mild steel laser cut and CNC profiled to ensure the tightest fit and best performance. Finished in heavy-duty powder coating. 11 fastening points for each rail using 7/16th grade 8 zinc plated hardware. Can be used as jacking points. This product comes with two frame rails per unit ordered. Now with provisions for fuel line clips on passengers side rail.


New Gen2 rails – We’ve updated the outer edge for a scalloped edge to better conform to the uneven uni-body surface. Added reliefs for the stock fuel & brake line mounting points. Improved fitment to the trailing edge of the rails to suit the OEM structure.

Here are our official Frame Rail installation instructions. Here’s another great write-up on how to install these rails on your MX-5.

Well made! Ordered unpainted rails to mount a custom transmission subframe for an ar5 transmission. These will make it super easy.

Perfect product! Although it's steel and not stainless which I heard from a couple of friends to be concerning, the coating when installed right you shouldn't have a bit of an issue. Very heavy duty product, and very affordable. Always +1 with V8R. The stiffness it adds to the car is night and day. This should honestly be a first mod

Holy f#

First of all I’ve bought these twice now for two separate Miata’s . Hands down one of the first mods that should be done . It’s easy to do with two ppl ,it took alittle longer to do it myself second time. Do your self a favor and get an impact gun so you can get them pretty much welded in ! The feeling of stiffness is night and day . 10/10 would make my friend get a pair also.

Excellent product. All the nuts and bolts were included.
Fast delivery.

It fits perfectly my Miata 1990.

Merci beaucoup.

solid frame

Lots of hard work for two people setting frame, drilling holes and torquing bolts. Hopefully this will improve the overall performance.
